Delphi to contest pressure to file U.S. taxes despite UK tax base

(Reuters) - Auto parts supplier Delphi Automotive Plc said it would "vigorously contest" pressure by U.S. tax authorities to file taxes in the United States as a domestic company, when its tax base is in the UK.

The Internal Revenue Service told Delphi in June that it would be taxed as a U.S. company due to the sale of its assets to Delphi Holdings LLC after it emerged from bankruptcy in 2009, the company said in a regulatory filing on July 31.

Delphi said it was reincorporated in the UK as a limited liability partnership, which allows it to save tax. The company said it had filed U.S. federal partnership tax returns between 2009 and 2011.

"We will continue to prepare and file our financial statements on the basis that neither Delphi Automotive LLP nor Delphi Automotive Plc is a domestic corporation for U.S. federal income tax purposes," the company said in the filing.

Delphi, which operates out of Detroit, is one among several American companies locked in a battle with the IRS over the use of offshore tax shelters.
